Empty value for an array

[Stanfillirenfro]

Hello!

I have a piece of code from MT4.
I have a line with the expression

if (Low[i] == EMPTY_VALUE)

Usually, I transform "Low[i] = EMPTY_VALUE" to Low.Reset(i);
But this will not be possible with a boolean.

Coluld someone advise me how to replace the term"EMPTY_VALUE"?

Thanks in davnace.

Hello Stanfillirenfro,

Thank you for your note.

A bool can only be one of the two values, either true or false. If you need some kind of special flag you will need to use an Int series and use 1,0, and -1 for the sentinel value.

Please let us know if we may be of further assistance to you.

Many thanks Kate for your reply.

For the boolean it is clear. But let's imagine that I do not have any boolean.

Please what could e the equivalent of "EMPTY_VALUE" in Ninjatrader?

Thanks!

Hello Stanfillirenfro,

Thank you for your reply.

As mentioned previously, you could use an int series instead of a bool. Set it to 1 when the bool would be true, -1 if false, and 0 for empty.
